Patented Mar. 10, 1931 UNITED STATES JOSEPH A. WHITE, OF BERKELEY, CALIFORNIA PLASTER BASE Application filed April 9, 1928. Serial No. 268,604.

The present invention relates to improvements in a plaster base, and its principal object is to provide a supporting and anchor ing means for plaster, stucco, and the like, that will be simple in its application, of permanent character, and tiiat will make a building absolutely fire-proof.

It is particularly proposed in this connec tion to provide a plaster base in which a metal plate is used for supporting in spaced relation thereto wire mesh or any other anchoring means for the plaster or stucco. It is further proposed to arrange the plaster base in such a manner that the entire framework of the house is completely surrounded on the inside and on the outside by a solid metal wall to which the cement or the plaster or stucco is held by suitable anchoring means.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanying drawing, in which Figure 1 shows a fragmentary view of my plaster base as applied to the studdings of a building.

Figure 2 an end elevation of my plaster base, and

Figure 3 a sectional detail View as seen from line 3-3 of Figure 1.

While I have shown only the preferred form of the invention, 1 wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

In its preferred form, my plaster base comprises a metal sheet 1 preferably made of a width corresponding to the distance between two adjacent studdings of a building 2 or any multiple thereof, and a wire netting 3 supported in spaced relation thereto. The wire netting is preferably secured to the metal sheet by indenting the wire netting along certain lines as shown at 4c and by fastening the extremities of the indentations to the metal sheet as shown at 6. It is not necessary that all the strands at the bottom line of the in- 0 dentations be fastened, as will be seen from the drawing. -The fastening may be accomplished by various dilferent means, but I prefer to weld the wire to the backing.

The manner of using my invention will be readily understood from the drawing and the foregoing description. The metal sheet 1, which may be of any desired height, is fastoned over the edges of two adjacent studdings and nailed as shown at 7, the backing sutiiciently wide so that two adjacent ones overlap on the studding. T his operation is all that is necessary, and after the plaster base has been applied, the entire frame structure of the building is'surrounded by a sheet of metal on the outside, while the inside is also covered with a metal coat which renders the entire building absolutely fire-proof. The plaster or stucco is then applied to the surface of the plaster base and is made to anchor in the wire netting.

' I claim:

1. A plaster base comprising a metal sheet, and a flat piece of wire netting furrowed as a unitso as to present spaced grooves and having the strands of wire forming the grooves welded to the metal sheet.

2. A plaster base comprising a metal sheet and a wire netting having projecting sections welded to the metal sheet.
